A Pro Series II model, t' Star Orbiter was me first rocket capable o' usin' 29 mm motors.  I upgraded t' Estes kit by addin' an ejection baffle and Keelhaul®©™ shock cord. 

Light-weight for its size, it flies well on 24 mm D12-5 and E12-6 motors usin' an available Estes engine adapter and a 48" long x 1/4" diameter launch rod.

T' Star Orbiter can also be flown as a cloud piercin' two-stage rocket usin' t' Estes Pro Series II booster and an E16-0 or F15-0 motor. 

I can't wait for t' next Club meetin' t' launch it with a 29 mm E16-6 or F15-8 motor.
